Little confused, am I. Original SW Trilogy vehicles (and a few Ep. VII subjects) are covered with high fidelity by the recent Bandai range (mostly 1/72 scale vehicles and 1/12 figures...plus others) which can be obtained via various online shops, including Amazon. The recent Revell range, which was designed for a "different demographic" - or perhaps a less 'demanding' one - aren't bad depictions of some of the Ep. VII vehicles and will have their uses. They just are simplified and gimmicky & hence tend to fall into the 'a model with play value' arena. I'm not a fan of the 'box scale' approach either, though there is the argument that such things have no "scale" being fictional... ahem, a discussion for another thread. The latest & most expensive (1/48 OT X-wing, TIE Fighter & 1/72 Millennium Falcon) are reboxed Fine Molds kits and hence have all the qualities of those kits at an even greater price than the originals. Perhaps Revell must buy them retail from FM and then take them out of the original boxes... ;^P
Anyway. Point is, I suppose, that several ranges of kits from AMT, MPC, Revell, FM & now Bandai offer a wide range of choices from the OT, the prequels and now (a few) from Ep. VII. The kits are products of the times when they were produced. For example, I just the past week found an example of the MPC A-Wing kit on my local hobby shop's 'bargain' table for $10. Until the kit by Bandai (or a resin garage kit), this was the only one available of this subject, barring building from scratch. It is a snap-tite design, simple with few parts but surprising accurate & showing evidence the original filming miniature was referenced. It is also a 1990-ish kit with the name 'ERTL' molded on the sprues so no high-precision fit is included or expected. Unlike the highly engineered product Bandai will provide which will undoubtedly "fall together", this MPC kit must be 'built' and 'worked' if a high standard is desired - or just stuck together and then 'zoomed' about. It is up to the modeler.
As a fan of 1/48 scale, Star Wars has always been a ragged journey. Bandai's efforts are a microcosm of that journey in that they have released a total of three OT subjects as kits. Of these wonders of modern kit manufacture, only one was not previously addressed (the Snowspeeder) in the scale. Granted, the X-Wing & AT-ST kits essentially made my stashed FM & MPC kits obsolete, so there was joy in each release. But then it was 'bitters' when no more 1/48 scale kits seem forthcoming - as is confirmed with each new announcement. There it is, the 'hit and miss' in a nutshell. (Nut is probably the perfect appellation!)
Such is this sore wound, I am reduced to converting SW toys (Hasbro seems to have a wonderful knack for making toys that turn out just the right size...) & measuring Hallmark decorations for 'scale'. Further afield then are the arguably 1/48 Hasbro 'Heros' Millennium Falcon, the 'Rise of Bobba Fett' Slave I and the Multi-Troop Transport (MTT) w/ compliment of 20 droid figures, all spot-on for scale and reasonably well detailed. More challenging is the 'transformer' General Grevious Starfighter toy (seams are huge...) Undoubtedly there are other candidates.
And then there are the 'paper' models!
